Over the past 12 years, the incidence of traumatic brain injuries (TBI) has increased from an annual rate of 500,000 to 1,000,000 new cases a year. This project will focus primarily on people that have sustained a traumatic brain injury and recovered to the Glasgow Coma Scale (GCS) level of 11 or better six months post-injury. With the needs of the target population in mind, the project team proposes the following project to develop the CAIRN, the context-aware independence recovery network to assist people who have sustained a moderate head injury regain an independent lifestyle. The CAIRN project will initially be focused on inferring context from multiple sensors, both worn and environmental, to direct memory cueing and sequencing but it will build the framework to assist, on a number of other axes, the individual on the road to recovery and functional independence.
